A train starts from Delhi at 6 : 00 AM and reaches Ambala Cantt at 10 AM. The other train starts from Ambala Cantt at 8 AM and reaches Delhi at 11:30 PM. If the distance between Delhi and Ambala Cantt. is 200 km, then at what time did the two trains meet each other ?

The energy density at a point in a medium of dielectric constant 6 is 26.55xx10^(6)J//m^(3) . What is the electric field intensity at that point ? [epsi_(0)=8.85xx10^(-12)SI units]

A capacitor of capacitance C=15pF is charged with voltage V=500V . The electric field inside the capacitor with dielectric is 10^(6)V//m and the area of the plate 10^(-4)m^(2) , then the dielectric constant of the medium is : (._(epsilon0)=8.85xx10^(-12) in S.I units) (A) 12.47 (B) 8.47 (C) 10.85 (D) 14.85
